Elements & Mitigation Plan Update

These project updates will utilize the latest updated hazard mapping resources, consistent with state law and federal requirements, and will lead to the implementation of effective mitigation projects and climate adaptation strategies. The County and its jurisdictions will utilize this new Multi-Jurisdictional Local Hazard Mitigation Plan (LHMP) and Safety Element Update to address hazards in a coordinated effort using a whole community approach that will be built on the public’s participation in the planning process.

As part of the planning process, other local agencies, neighboring jurisdictions, and stakeholders are involved to raise awareness of this effort and provide an opportunity for input. In addition, an objective of this outreach is to coordinate with those who may bring additional information to the planning process regarding hazard issues or hazard mitigation efforts within the County.

Mineral Resource Designation Amendment

Formerly referred to as the "Mining Designation Amendment", this is a modification to the Land Use Ordinance, Coastal Zone Land Use Ordinance, and General Plan relating to the Energy and Extractive Resource (EX) and Extractive Resource Area (EX-1) combining designations.  The project will include the following components:

  1. Adjust the EX-1 boundary maps to reflect state-designated regionally significant mineral resources. 
  2. Make editorial changes to policy language for clarity and consistency. 
  3. Add language regarding agricultural land use compatibility in the Santa Maria River valley. 
  4. Add language regarding urban land use compatibility in Creston. 
  5. Clarify that the intent of the combining designations is to preserve mineral resources, rather than to expedite extraction projects. 
  6. Distinguish between the EX and EX-1 designations and potentially rename them. 
  7. Address impingement of residential uses in areas with significant mineral resources. 

Oster/Las Pilitas Quarry

A request by Las Pilitas, LLC for a Conditional Use Permit and Reclamation Plan to allow for a new aggregate quarry and asphalt and concrete recycling facility. Mining operations would occur over a 30-year timeframe and conclude with reclamation of the site. The maximum annual extraction would be 500,000 tons. The project would result in disturbance of roughly 60 acres on two parcels totaling 203 acres in size. The project site is located east of the community of Santa Margarita at 6660 Calf Canyon Highway (Highway 58, north side), east of the Salinas River Bridge and approximately 0.25 miles west of Parkhill Road.

Sign Ordinance Update

The Sign Ordinance Update is a targeted effort to revise the County’s sign regulations to comply with federal law and protect the constitutional right of free speech. In 2015, the U.S. Supreme Court Case Reed v. Town of Gilbert required local jurisdictions to be content-neutral when regulating signs (for example, not regulating a sign based on whether it carries a commercial, political, or ideological message). The Sign Ordinance Update will ensure the County’s regulations uphold constitutional speech, while also protecting the visual character of the community.

Somera/The Cottages Hotel

A request by SCM Avila Beach Partners, LLC for a Development Plan/ Coastal Development Permit for the construction of a 50-room cottage style hotel, temporary events not exceeding 200 guests and modification of side and rear setback standards. The applicant is also requesting a Variance to grade over 30% slopes and an Amendment to the San Luis Bay Estates Master Development Plan to increase the potential development area from the previously approved 4 acres to 7 acres.  The project will result in the disturbance of approximately 7 acres on the 22.25-acre parcel with an approximate of 20,300 cubic yards of cut and 18,000 cubic yards of fill. The project site is in the Recreation land use category and is located approximately 620 feet northwest of the Avila Beach Drive and Ana Bay Drive intersection in the community of Avila Beach.
